    Laccases can functionalize paper pulps with phenolic compounds but little is known about the formed linkages. Treatment of a high-kappa sisal pulp with Trametes villosa laccase and ferulic acid resulted in strong increases ...
  • Biomodification of cellulose flax fibers by a new cellulase 

    García Ubasart, Jordi; Torres López, Antonio Luis; Vila, Carlos; Pastor, Francisco J.; Vidal Lluciá, Teresa (2013-01)
    Article
    Accés restringit per política de l'editorial
    The potential of the new cellulase Cel9B from Paenibacillus barcinonensis for the modification of cellulose flax fibers was for the first time assessed in this work. Cel9B treatments were found to enhance the development ...
  • Biorefinery: the paper mill of tomorrow

  • Effect of the laccase mediator system on the fibre properties of TCF bleached kraft pulp 

    Cadena Chamorro, Edith Marleny; Cusola Aumedes, Oriol; Vidal Lluciá, Teresa; Torres López, Antonio Luis (2011)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    The application of the laccase mediator system (L stage) to TCF bleached pulp from Eucalyptus globulus with a low residual lignin content provides useful information about its effect in the hexenuronic acids content, ...
  • Effects of a cellulase treatment on the preparation process and final properties of nanocrystalline cellulose 

    Beltramino Heffes, Facundo; Roncero Vivero, María Blanca; Vidal Lluciá, Teresa; Torres López, Antonio Luis; Valls Vidal, Cristina (2015)
    Comunicació de congrés
    Accés restringit per política de l'editorial
    In this work, we introduced an enzymatic treatment with a cellulase prior to NCC isolation from fibers via sulfuric acid hydrolysis, combining biotechnological and chemical procedures. NCC isolation process has typically ...
  • Increasing yield of nanocrystalline cellulose preparation process by a cellulase pretreatment 

    Beltramino Heffes, Facundo; Roncero Vivero, María Blanca; Vidal Lluciá, Teresa; Torres López, Antonio Luis; Valls Vidal, Cristina (2015-06-09)
    Article
    Accés obert
    In this work the introduction of a cellulase treatment prior to NCC isolation was assessed. NCC was produced using sulfuric acid at two different concentrations (62 and 64% wt.). The effect of pore size for filtration step ...
